Microsoft co-founder Bill Gates retains the top spot on the Forbes list of America’s 400 richest people for the 22nd straight year with Republican presidential frontrunner Donald Trump ranked 121st with $4.5 billion.

While Gates’ worth is assessed at $76 billion, down $5 billion from 2014, Trump’s is put at $4.5 billion – less than half of what he has been claiming.
